1 Claim. (Cl. 229-48) My inventicn is a division of Patent No. 2,236,557, issued April 1. 1941, and relates to novel structural members, .and more particularly to novel securing and reinforcing metalic` members to be used in connection with collapsible and/or folding containers of sheet material: and

to collapsible and/or folding containers of shet material using my novel structural members,

In my copending appl'cation. now Patent No. 2,233,906, issued March 4. 1941, of which the application is a continuation in part, reinforcingr members having bayonet prongs cooperating with suitable slots are shown' as means connectln several parts of a ling drawer.

These means of securing the several parts of a tiling drawer may be appl'ed also to other parts of folding containers, as well as being applied to ling drawers in other novel ways.

One portion of my prong and slut fastening means may be attached in the factory to one panel of a folding and/ or collapsible container; and the other portion attached in the factory to another part of panel which in its set up posit'on is to be united with the aforesaid panel. The container may then be easily set up and the proper parts firmly united with each other by the user.

Accordingly, objects of my invention are to prrvide a novel metallic fastening means for unting parts of a fold'ng 'and /or collapsible container: to combine said fastening means with other metallic members of the container performing other funtions, and thereby to reduce manufacturing costs: and in the fastening means to provide a device that may be easily and quickly assembled at the point of use,

There are other objects of my invention which together w'th the foregoing will appear in the detailed description following in connection with the drawing.

In the drawing, I have illustrated my invention in relationship to a ling casing, but it will be understood that my invention may be s im'larly applied to other folding and/or collapsible containers of sheet material. Thus it may be used with clothes cabinets, ice-cream containers.

Aclothes hampers, and other similar structures.

.My invention may be better explained by refern en'ce to the accompanying drawing. which forms Figure 4 vshows the blank of Figure 2, folded and about to be inserted in the casing of Figure 3;

Figure 5 shows an enlarged section on plane 5-5 of Figure 4.

Figure 6 shows an enlarged section on plano l 6 6 of Figure 4. y

Figure 7 shows an enlarged section on plane 1 1 of Figure 3.

Figure 8 shows an enlarged section on plan 8-8 of Figure 3.

Figure 9 shows in elevation a fragmentary sheet with a modfled form of slot for receiving a bayonet prong.

Figure 10 is a cross-section on the line` I tl-I of Figure 9, showing the bayonet in the slot.

Figure l1 shows a modified form of bayonet or use with the form of slot shown in Fizure 9.

Referring now to Figures l to 8, I have shown several modifications of my ybayonet securing means as appled to the casing for a ling drawer. In Figure 1, 'lll is a blank of material having parallel score lines 1I, 12 and I3 dening the top panel 11, the bottom panel and the two side panels 14 and 16.

Around the open front end are the horizontal reinforcing members T8 and l9 vertical reinforcing members 8D and 8l, and angular corner wire 82 and 83. all as fully described in Patent. No. 2233.996 issued March 4. 1941.

Along the rear edge of the top and bottom panel are the hor'zontal reinforcing members 84 and 85 pressed onto the blank 'l0 of sheet material. Member 84 has an outstanding flange 8B and member 85 has outstanding ange 81, each ange having a line of slots 88.

Along top edge ci' the side wall 'ld is metallic member 89 having the line of sots 90, and pressed lug 93 as has alreadybeen described in connection with the other gures. Member 9| may be attached to the blank 'lll in the same manner as dei scribed for member 89. To set the blank up into tubular form it is necessary merely to bend the sheet on its score lines so that the bayonets of member 9| will register with the slots of member 89. On stabbing the bayonets into the slots, the blank will take the tubular shape shown in Figure 3, after which the front end reinforcement may be set in its operating position. With the joint formed by the members 88 and 9|, the blank may pleted by members -89 and 9|, or by a tape at the joint where panel 11 and panel 14 meet.

The blank 94 is provided with the score lines 96, 91, 98 and 99 which define the back panel 95 and the top flap |00, the bottom flap and the side flaps |02 and |03. The top and bottom fiaps are each provided with the U shaped metal member |04; and the side naps |02 and |03 are provided with the U shaped metal member |05.

Metal members 04 are attached to the top and bottom flaps (on the near side as viewed in Figure 2) by means of the prongs |06 formed from the metal of the member. The members |04 are substantially coterminous with the flaps to which they are attached, except for the bayonet tongues |01 which extend beyond the bend line. The metal extends over the edge of the flap at |08. This provides a finish for the edge of the iiap |00 and reinforcement for the casing. The tongues |01 have a locking lug |09.

Metal members |05 are attached to side flaps (on the far side as viewed in Figure 2). The short leg l|0 of the U projects around the flap so as to be viewed from the near side in Figure 2. Members |05 are attached to the flaps by means of the prongs To set up the back member, the aps are bent on the respective score lines which will produce a structure shaped as a shallow pan, as shown in Figure 4, which is viewed from the side opposite that shown in Figure 2. In this position, the bayonets |01 project beyond the inner face of the rear panel along the top and bottom edges of the panel; and the U shaped members |05 project beyond the sides of the back panel.

In this position the back panel will fit snugly within the open rear end of the casing tube with the U shaped members 05 iitting around the rear edge of the side panels 14 and 16 and with the bayonet tongues |01 of the strips |04 registering with the slots 88 in the metal strips 84 and 85 attached to the rear edge of the top and bottom wall of the casing.

It is thus necessary merely to push the rear end member into the tube to attach the rear end to the tube. When the bayonets have been projected into the slots for the proper distances the locking lugs |09-will spring into place back of the slots and thus iirmly hold the rear end in place against withdrawal. The angles 86 and 81 on members 84 and 85, and the channels 05 will prevent the rear end member from being pushed too far within the tube. The metallic members |04 and |05 around the rear end of the casing will provide a finished appearance to the rear end. In Figures -9, 10 and 11, I have shown a form of bayonet and slot construction in which the slot has a resilient edge adapted to retain the bayonet in position with respect to the slot. The principle used in this construction is that which I have disclosed as a means for attaching a metallic reinforcing to a cabinet wall in my copending application, now Patent No. 2,159,069, issued May 23, 1939.

Referring to Figures 9 and 10, plate ||2 represents a portion of the member with which the bayonet coacts. Each slot in this member is produced by making two spaced slits I3 and ||4. Substantially midway of these spaced slits is a third slit perpendicular to and uniting these two slits. The metal on each side of the latter slit is bent back out of the plane of the sheet (as at ||6 and ||1 of Figure 10) forming the slot IIS, which should be somewhat narrower than the prong with which it is adapted to coact. Thus when the prong ||8 is pushed into the slot, the wings ||6 and I |1 are further displaced; and are firmly held by their elastic nature in intimate contact with the bayonet. The edges ||9 of the slot ||5 thus grip the prong ||8, and hold the prong I8 in substantially xed relationship with the slot ||5 in the plate H2,

In Figure 10, I have shown the prong |I8 as being a substantially smooth member, with the pressure of the wings ||6 and ||1 being relied upon to maintain relative position of the prong and the slot. Where greater holding power is required the prong may be provided with notches as at |20 of Figure 1l. Thus when a prong or bayonet ||8a as shown in this figure is inserted in slot |5, the edges ||9 of the slot fall into notches |20 and more firmly hold the bayonet in place, than is the case where no such notches are provided.

It will be understood that the illustrations described are by way of example only and that I do not limit my invention to the particular forms and applications shown, as my invention may be widely modified and applied within the scope and meaning of the appended claim.

I claim:

A folding container of sheet material comprising two parallel walls united with each other through structural means; a metallic member at the edge of each of said parallel walls, each of said metallic members having an upturned flange having a line of slots therein; a separate member for forming a wall of said container connecting the said metallic members; said separate member having a flange along two parallel edges, said flanges having metallic members having bayonets for registering with said slots, and means of locking said bayonets in said slots when said bayonets are inserted into said slots, whereby said separate vmember is united with said two parallel walls.
